Milter-greylist

It appears that there is a bug in the way from addresses are parsed if
an equals sign appears in them.

Example:

Feb 10 08:38:35 mxa milter-greylist: j1AGcYDf023468: addr 64.192.229.17 
from =windwireless.net@...> rcpt <user@...>: 
autowhitelisted for more 120:00:00
Feb 10 08:38:36 mxa sendmail[23468]: j1AGcYDf023468: 
from=<bounce-9985-user=windwireless.net@...>, size=6682, 
class=0, nrcpts=1, 
msgid=<200502101638.j1AGcYDf023468@...>, proto=SMTP, 
daemon=MTA, relay=mta1.m.freeride.com [64.192.229.17]

   Sendmail correctly shows the entire from address, the milter is only
getting the tail end of it starting at the equals sign.  I checked in
the greylist.db file, it's broken there also.
